AssEMBLIne MACHINE non SHA E-ROLLER FITTINGS.

Application filed April 14, 1927. Serial No. 183,696.

This invention relates to assembling 'machines for shade roller fittings.

Objects of this invention are to provide an assembling machine for shade rollers which is so constructed that the machine will readily drive the end pin centrally into the shade roller and will correctly position the roller with reference to the pin prior to the driving operation so that the pin is absolutely centered at the instant that it enters the roller. v

Further objects are to provide a machine which automatically grips the roller when the cross head or moving portion thereof is depressed and which automatically releases the roller when the cross head rises to its next position.

Further objects are to provide a machine which is so constructed that an operator may place the ferrules and end pins correctly with reference to the roller with the utmost speed and facility and in which means are provided which furnishes a holder for the pins and ferrules and which is detachably mount- 25 ed upon the n'iachine, so that it may be quickly removed and carried to the stock room and refilled.

Further objects are to provide a novel form of assembling machine for shade roller fittings in which means are provided for gripping the pins of old rollers so thatthey may be readily removed in the event that repair jobs are done, and in which an end tapering instrurnentially is carried in a readily accessible position upon the machine, so that in the event that the ends of the rollers are roughened or irregular they may be readily tapered in a simple manner at the same machine that is used for positioning the end pins.

An embodiment of the invention is shown in the accompanying drawings in which:

Figure 1 is a front elevation of the machine with parts broken away and in section;

Figure 2 is a View from the upper rear portion of the machine;

Fi ure 3 is an enlarged sectional view of the foot or holder which centers the lower end of the roller and of the anvil and ad-.

parts broken away and with the ferrule and pin holding tray removed Figure 5 is a sectional View on the line 55 of Figure 1; Figure 6 is a fragmentary sectional View on the line 6- 6 ofFigure 1 Figure 7 is a sectional view on the line 7-7 of Figure 1;

Figure 8 is a sectional view on the line 88 ofFigure 5.

Referring to the drawings, it will be seen that themachine comprises a base 1 which is adapted to be securely attached to the floor and from which a main supporting standard 2 rises. This standard rigidly carries an adj ustably mounted anvilsupport 3 which is provided with an upwardly projecting anvil 1 provided with a recess 5 for the reception of the end of the trunnion pin or endpin 6, as shown in Figures 1 and 4. The member 3 is adjustably locked in place by means of the set screw 7 (see Figure 1) and carries a guide rod8 which is lockedby means of a set screw 9. The guide rod extends upwardly and its upper end is locked by'means of a set screw 10 to a top member or trip member 11.- This top member is provided with a pair of downwardly projecting arms 12 for tripping the gripping dogs in a manner hereinafter to .appear.'

A cross head 13 is slidably mounted upon the standard 2, as shown in Figures 1, 2, 4t, and 5. This cross head '13 is providedwith a pair of rock shafts 14, as shown most clearly in Figure 5, which at their forward ends carry the grippin dogs 15, and at their rear ends carry the weighted levers 16. These weighted levers are provided with inwardly projecting extensions or ears 17 which are adapted to contact with the lugs 12 when the cross head is in its uppermost position, as shown in Figure 2, to thus rock the shafts'li and release the gripping dogs from engagement with the roller 18. From Figures 1 and 5, it is clear that the grip riing dogs 15 are provided with concave faces contacting with the roller, and that these faces are rounded, as shown most clearly in Figure 1. The faces are serrated, as indicated by the reference character 19 in Figure 1, and also eccentric with reference to the shafts 14, so that they will bind {when the cros till head is pulled downwardly. This cross head 13, as may be seen from Figures l and 5, is provided with a rearwardly projecting ear or lug 20 which slidably fits the guide rod 8 and thus is prevented from turning.

Immediately below the. cross head and between such cross head and the anvil 4, a supporting foot 21 is provided for the lower end of the roller. This supporting foot is provided with a tapered inner surface :2 of conical contour and is rigid with a tubular portion 23 slidably mounted upon the standard 2. It is also provided with a rearwardly projecting ear :24 slidably guided by the rod 8. A colled spring is positioned between the member 25 and the slidably carried shoe and normally holds the shoe above the anvil, as shown in Figures 1 and 4-.

It is to be noted that the cross h ad is moved, preferably by i'neans oi a foot lever pivoted to lugs carried by the base. as shown in Figure -l-, and spring urged up wardly by means of the spring 27. This foot lever is connected by means of rods 2:; with the cross head 13, the rods being located on opposite sides of the central standard 2, as shown in Figure l.

From the mechanism thus far described. it is apparent that a roller l8 with the end ferrule 29 in place may be readily slipped downwardly between the dogs If and coin tered by means of the tapered inner suri'ru-e of the shoe 21. An end pin (3 is positioned within the aperture 5 of the anvil l and its integral flange 30 rests upon the upper surface of the anvil, as shown in Figures 1 and 3. The operator now steps upon the foot. lever or treadle and the cross head descends, causing the dogs 15 to grip the roller. The roller is thus carried down by the cross head with its end bearing against the spring pressed shoe 21 and correctly held with reference to the end pin (3. The end pin is thus forced into the descending roller, the shoe 21 yielding or moving downwardly into the position shown in Figure 3. Thereafter, the operator removes his foot from the treadle and the cross head and shoe spring upwardly carrying the roller with them. At the extreme upper motion of the cross head, the ears 1? of the weighted levers 16 strike the projections 12 and thus rock the dogs 15 into disengaging position permitting tree removal of the roller.

In order to provide for the accurate guiding of the upper portion of rollers of dift'erent sizes, a removable bushing or member 31 (see Figure 5) is carried by the Cross head 13. This member or bushing fits within the curved arms of the cross head 13 and is held in place by spring clips 32. as shown most clearly in Figures 5 and 8. These bushings are adapted to be interchanged to tit rollers of different sizes.

It is to be noted also from Figures 1, a

and (i, that an adjustably mounted sleeve 33 is locked by means of a set screw 34 to the standard at a point below the member 3. and is provided with a dovetailed portion 35 which detach-ably engages the correspondingly (.lovetailcd portion 36 of a holder 37. The holder 37 is provided with end compartments 38 which are adapted to carry a supply of ferrules, and with a central co1n partment 39 which is adapted to carry pins or end trm'n'iions tor the shade rollers. Thi. holder may be most easily detached from the member 33 and carried to the stock room where it may be refilled. it is equally easy to reposition the holder 37 by slipping its dovetailed slotted portion 36 over the dovetailed projecting part do of the member 33, as shown most clearly in l igurc (3.

Below the member 33, a bevelling device 40 is iuljustably positioned and locked by means of its set screw 41, as shown in Figure 4. This bcvelling device is provided with a. fluted conical portion 42 with the flutes relatively sharp or knife-like, so that they will trim the lower end of a roller and will slightly bevel such lower end to remove any ragged portions and to facilitate the entrance of the end of the roller into the ferrules.

It sometimes happens that repair wort; is done upon this machine and means must be therefore provided for extracting the end pins of the old rollers. This is readily areomplished by means of the auxiliary foot. lever l3 which is provided with a gripping jaw ll cooperating with the stationary gripping jaw carried by the base 1, as shown in Figure 4-. The foot lever 43 is urged into jaw open position by means of a spring. in usin this device the end pin of the old shade roller is positioned between the jaws ll and 45 and the operator then steps upon the auxiliary foot lever 43, thus gripping the end pin. He may thereafter pull upwardly upon the shade roller with an easy and natural motion and may thus very readily extract the end pin from the old roller.

It will be seen that a novel machine has been provided which may be very rapidly and easily operated to assemble shade rollers and which may be used for repair work with the utmost facility.

1t will be seen further that the device is semi-automatic in its operation and that the minimum oi etl'ort and thought is required on the part of the operator, so that. an unskilled operator may produce work of standard quality with the greatest ease.

Altl'iough the invention has been described in considerable detail. such description is intended as illustrative rather than limiting as the inventon may be variously embodied and as the scope of such invention is to be determined as claimed.
